Everyone already knows the Spring model of the Romanian manufacturer Dacia and it is no longer a surprise that it stormed the Romanian electric car market.

Of course, there are criticisms related to Dacia Spring, especially since the car is produced in China and we all know the reluctance of buyers toward Chinese products. The manufacturer's decision to brand and then sell the Spring model under the Dacia logo proved successful as the model entered the top 10 most registered electric vehicles in Europe in 2022.

On the Romanian market, Spring is by far the most beloved model, both due to the affordable purchase price and the technical specifications that cover most urban mobility needs. Over 30% of the electric car fleet is represented by Dacia Spring in Romania.

With the help of our partners from Auto Europa Timișoara, we also had the chance to test the Dacia Spring for a week and find out if it really covers most use cases.
Our colleagues from SafeFleet provided us with a GPS monitoring device to collect statistical data on our journeys.

The tests we conducted were divided into two usage categories: company car and private car.

Dacia Spring as a company car

The user was our colleague Bogdan, who is part of the technical department and had a trip from Timișoara to Arad to check one of the chargers installed at Moemax Arad.

Bogdan charged the car battery at one of the stations installed in the parking lot of our headquarters and traveled 75 km to his destination. This distance was traveled on the highway with maximum speeds between 100-110 km/h.
On the way back, he decided to change the route and drove on the national road between Arad and Timisoara to avoid the congestion at the motorway exit, thus driving 57 km to our office.

The travel data can be found in the following table:

The running costs for our colleague's trip were 32.4 RON/100km, equivalent to a consumption of 3.7 l/100km considering the petrol price of 8.65 RON/l. Charging was carried out at the fast charger in our office car park, with an electricity cost of 2.19 RON/kWh.

You can read more about the whole trip and Bogdan's opinion about Dacia Spring in the discussion at the end of the article.

Dacia Spring as a private car

During the time I've used this car, I've used it normally, for commuting, shopping, sightseeing, and peri-urban trips.
We drove a total of 286 km with a consumption of 13.3 kWh/100km. This consumption gives a theoretical maximum range of about 200 km, which is enough for normal travel needs, given that the European average is around 30 km/day.

What's interesting to note is that in one week, while we had the car for testing, the driving time was 14h15min and the stationary time was 151h57min (about 6 days). The car was stationary 91% of the time when the average daily distance traveled was almost 60km/day, double the European average.

This gives the user plenty of time to charge the car when at work or sleeping. While the car was stationary, its battery could have been fully charged 38 (thirty-eight) times!

The following table shows the distances traveled between charges, the energy charged, the travel time, and the stationary time of the vehicle.
The charges were carried out at home at an electricity tariff of 1 RON/kWh, which gives a running cost of 13.3 RON/100km or the equivalent of 1.5 l/100km of petrol.

Altogether, our team drove 418 km in the Dacia Spring, so we could objectively assess the model.

First of all, the purpose and price of the car should be taken into account. Being a budget car, it should be judged as such, and comparisons with premium used cars at the same price are pointless.
At the moment, the Dacia Spring is unrivaled in this compact, city segment, being the most affordable variant, while still offering enough driving range, good safety features, instant acceleration, and a mobile app for climate control and charging.

Running costs must also be taken into account, which for electric cars are much lower than for those equipped with internal combustion engines. The 418 km covered by the Dacia Spring can cost between RON 37 and RON 130, depending on where you charge and the electricity tariff.

We believe the Dacia Spring is the ideal car for last-mile delivery fleets, food deliveries, service, and intervention cars, but also for private users who spend most of their time driving within cities and we encourage all companies to consider electrifying their fleets, as we have also been doing.

Watch the following video for images and opinions from our experience with the beloved Dacia Spring.

All charging was done at LEKTRI.CO network stations or at home with the LEKTRI.CO 1P7K charger. Dacia Spring charges at AC stations with a maximum power of 7 kW, having a single-phase OBC, so there is no need for expensive, three-phase, high-power stations to charge at home.

To help everyone be on the same page with electric vehicle terms, we created a list that explains the most common ones. From AC to ZE, we present it all!

We’ll start with the ones related to electric current:

AC stands for alternating current, which is the type of electric current you'll find at any electrical outlet.

DC, or direct current, is the type of electricity that can be stored in batteries.

Electric cars store electricity in the form of direct current. They can either be charged at AC or DC chargers. To charge from an AC charger, the current must be converted to DC. This process is done by a device inside the car called on board charger, or OBC. We at LEKTRI.CO develop and produce AC chargers.

Please also check the last section of this post to find out more about two of the most important units when it comes to electric vehicles.

In the next section, we will look at some special terms for electric vehicles.

There are lots more acronyms you can use when talking about electric vehicles, the most common being the aforementioned. ULEV and ZEV are also used when talking about ultra-low emission vehicles or zero-emission vehicles, but they're not so common.

When talking about BEVs there are some terms worth mentioning about the current state of the battery:

When it comes to charging standards, AC and DC are the two main categories:

AC
DC
Type 2 - Europe
CCS (type 2) - Europe
J1772 (type 1) - USA
CCS (type 1) - USA
J1772 (type 1) - Japan
CHAdeMO - Japan
GB/T - China
GB/T - China

CCS - combined charging system is basically a type 2 (for Europe) or type 1 (for the USA) with two additional direct current pins at the bottom.

A confusion many people make, not necessarily because of lack of knowledge, is between the measuring units of power and energy.
Power, used when charging the battery or as an indication of how powerful a motor is, is measured in kilowatt, although the SI unit (International System of Units) is Watt.
Energy on the other hand is measured in kilowatt-hour or Watt-hour for the SI unit.

So when talking about charging power, whether it's AC or DC, you should use kilowatts (kW); and when talking about battery capacity, energy consumption, or efficiency, you should use kilowatt-hours (kWh).

EV charger protections and safety elements are among the most important things to look for when buying an electric vehicle charging station.

As the EV industry grows, there is a lot of attention (for good reasons) on the EV charging station itself.

However, there's another aspect to consider that many vendors may get wrong: safety. You, as an end-user, want to be safe while charging, and you also wish the charger not to present any danger to the public or your property.

Many manufacturers claim their chargers have all the necessary safety features, but not all respect every safety standard.

Furthermore, you may want to double-check if the chosen charging station indeed incorporates a 6 mA DC leakage detection device.

This will dictate what type of RCD you need to use to protect yourself and your family, as the price between the two classes in question varies drastically, often as much as the cost of the charging station.

ev charger protection

The RCD (residual current device) can often be overlooked, but its importance is crucial in preventing serious harm due to electrical shock.

You may be thinking that the usual circuit breaker (MCB) installed in the consumer unit (fuse board) may be more than enough.

Still, the circuit breaker's goal is to protect the electrical system and wiring from overcurrent and short-circuits, whereas the RCD protects people and pets from electrocution.

So, what type of RCD should be chosen for adequate protection?

According to the IEC 61851 standard, any charging station must be protected against 6mA smooth DC and 30mA AC fault current.

The AC type RCD is not suited for electrical devices since it induces a pulsating direct current (DC) that is not detectable by this form of RCD and is even outlawed in some countries.

The A type works for most electronic devices, but specific devices might create a smooth DC current in the network, which can blind the type A RCD.

In such a case, the type A RCD would not trigger even when a fault has occurred. Faulty charging stations can sometimes cause higher DC currents, making this type useless.

The B type RCD is the go-to solution for safety when installing EV chargers, but it is also the most expensive. A good quality B type RCCB can cost around 500-600 €. But no price is too high for your safety, isn't it?

To protect our customers and their loved ones and save them the high cost of type B RCDs, our 1P7K charger has an integrated 6mA DC detection device (RDC-DD) so that it can be installed on any circuit protected by a type A RCD, which is often already installed in your home.

Our product, the 1P7K has an integrated RCD protection module that detects both 6mA DC and 30 mA AC. Surely, an A type RCCB has to be installed on the power supply, but this is way cheaper than the B type, usually around 20-30 €.

The integrated protection module within our charger makes sure the external protection is not “blinded” by the smooth residual DC.

The 1P7K also has integrated overheating protection meaning that if the charger overheats, it lowers the charging current until the temperature stabilizes. If the temperature does not drop enough, the charging stops, protecting your home and the charger from any damage.

Please check carefully when choosing your desired EV charger so it has all the necessary protections integrated and that it respects the standards accordingly. Otherwise, you might have to spend extra money on installing external devices or end up with a potentially dangerous charging station.

Elbilsvaruhuset.se and LEKTRI.CO has joined forces to serve its customers better. We provide the charging stations, and they take care of installation and assistance for receiving the Green Technology Grant.

When the number of electric vehicles increased rapidly in Sweden during 2021 - a 64% increase over the year, Elbilsvaruhuset.se saw a business opportunity and started its project to become the leading provider of reliable charging stations for electric cars.

To meet the demands of this growing market, new solutions are needed to provide users with a flexible and straightforward solution for charging electric vehicles at home. Nearly 90% of electric vehicle charging occurs when the car is parked at home or at work, so EV owners must be able to equip their homes with a safe and convenient charging solution.

LEKTRI.CO is a Romanian start-up based in Timisoara, which provides charging solutions for EV drivers and has started developing a complete ecosystem for EV drivers. This year we enter the Swedish market, with Elbilsvaruhuset being our crucial partner in providing AC chargers for public and private use.

The purchasing process is simplified for the consumer, with Elbilsvaruhuset.se assisting with all issues relating to charger supply and installation. They also assist in obtaining the environmental grant, known as the Green Technology Grant, which the Swedish Tax Agency issues to install green technology. The grant consists of a 50% price reduction if the same company provides the charger and the installation services.

As mentioned before, the charging station and installation have to come as a complete package, one product that includes the hardware and the installation services to benefit from the grant. Elbilsvaruhuset.se has an advantage over its competitors, and it partnered with Done for developing a unique digital solution to facilitate the buying process of charging systems for the home.

The way this partnership works is that Done offers free consultation through video calls with their selected electricians before the installation process starts. They then make a quote, so the customer gets price proposals as quickly as possible, and the customer then schedules the start of the project directly within Done’s mobile app.

We're thrilled to be working with Elbilsvaruhuset, our Swedish partner, to help develop the home charging infrastructure for EVs in the Nordics. We aim to provide the best charging solutions for our customers with this partnership.

LEKTRI.CO's vision of simple design and well build quality products resonates with our core values at elbilsvaruhuset.se. With this collaboration, we aim to give the Nordic people a good EV charger for a great value with a minimalistic design that people appreciate. Together we strive toward the same goals which are to facilitate the transition to electric driving for all private individuals and provide a simple service with the market's most affordable electric car charger
